The right rear passenger heated seat in my 2018 Audi Q7 overheated and burned through the leather and foam. Fortunately, my disabled [XXX] daughter, who normally sits in that seat, was not in the vehicle at the time. The failure occurred without warning and during normal use. This defect presents a serious safety risk and could have caused injury or fire. Request: Please investigate this issue in the 2018 Audi Q7 rear heated seats and determine whether a recall or repair campaign is necessary.

My 2018 Audi Q7 3.0T Quattro is experiencing extreme oil consumption — dropping from full to minimum level in approximately 230 miles. This is approximately 14x beyond Audi's own threshold for excessive oil consumption of 0.5 quarts per 1,000 miles. Documented timeline: May 2026 (88,692 miles): Oil change required 2.2 extra quarts beyond standard 7.2qt fill. Low oil light triggered during highway travel. June 27, 2026 (90,200 miles): Authorized Audi dealer formally documented "oil consumption is very high" in their service system and scheduled an official oil consumption test. June 28, 2026 (90,351 miles): Audi MMI system showed oil near minimum after only 151 miles. June 30, 2026 (90,397 miles): Audi MMI showed oil at Stage 2 warning after 197 miles. June 30, 2026 (90,430 miles): Audi MMI showed oil at minimum line after 230 miles total. All readings documented with timestamped photographs from Audi's own MMI system. The authorized Audi dealer has documented repeated oil top-offs in their service system. Audi USA Customer Care was contacted on June 30, 2026 and denied goodwill repair citing no active recall and vehicle out of warranty. An open case has been filed with Audi USA. The engine lubrication system appears defective. Oil dropping to minimum in under 230 miles without adequate warning poses serious safety risk of catastrophic engine failure while driving at highway speeds. The authorized Audi dealer has scheduled an official oil consumption test and inspection for July 2, 2026. Results will be available upon request. Vehicle is available for inspection upon request.

I am reporting suspected odometer fraud on my 2018 Audi Q7 3.0T Prestige (VIN: [XXX] ). Between May 8 and June 13, 2025, while I was the sole driver of the vehicle, Audi dealership service records show an odometer increase of 5,282 miles (from 78,260 to 83,542). However, independently verified GPS trip data from the Audi Connect system confirms I drove only approximately 2,103 miles during this period — a discrepancy of approximately 3,178 miles. The vehicle was serviced at two Penske-owned dealerships: Audi of Arlington (3200 Columbia Pike, Arlington, VA 22204) and Audi of Chantilly (14839 Stonecroft Center Ct, Chantilly, VA 20151). Only authorized dealer diagnostic equipment can alter odometer values. This manipulation resulted in the wrongful denial of my extended warranty coverage and a 37,567.16 out-of-pocket engine replacement. I have a fully documented demand letter with ten supporting exhibits including service records, Audi Connect trip data, and a detailed timeline. The dealerships did not respond to my demand letter.

SuspensionApr 2026 · ODI 11729693Details +

I’m reporting a serious safety issue with my 2018 Audi Q7. Both rear suspension springs failed suddenly while I was driving at highway speeds 70 MPH, with no warning at all. This was extremely dangerous—I almost lost control of the vehicle when it happened. The rear of the car dropped and handling became unstable immediately. There were no prior signs, noises, or issues leading up to the failure. This kind of failure should not happen under normal driving conditions, especially on a vehicle like this. Having both springs fail at the same time creates a major safety risk not only for me but for others on the road. I had to replace both rear springs at my own expense. Based on what I’ve seen, this may be a known issue and not just a one-time occurrence. I’m asking NHTSA to look into this problem and determine if there’s a defect with the suspension system on the 2018 Audi Q7 that could require a recall or further action.

The car has always (including during warranty period) required addition of engine oil in between scheduled maintenance interval, and problem got worse as function of age/miles. Audi has diagnosed this issue and it has been determined that the engine consumes excessive oil and requires new piston skirt. The cost of the labor is not something Audi is willing to pay for and there is a class action lawsuit. Audi has sent an email/letter to certain owners of the vehicle. My VIN for some reason wasn't included but now Audi has verified, but not willing to pay for the cost to replace the engine or fix it.

This vehicle developed low oil alerts within 6 weeks of me receiving it with normal city driving. Multiple testing visits and comprehensive consumption testing later, it continued to have the low oil alerts very frequently and various random malfunction alerts like parking brake alert etc. For each complaint I took it to the dealership and did whatever they recommended but no eventual resolution was found. Early October this year, in the middle of traffic multiple alerts came on including drive system malfunction, parking brake malfunction and start stop malfunction. So many that the whole console just lit up and the car started rocking in the middle of traffic and I had to slow down to keep the vehicle in control. The car was rocking visibly and I had difficulty in maneuvering it to a safe location . I contacted the dealership and they gave me an appointment 4 weeks out saying that since the lights were solid and not flashing I could choose to drive the car. However it didn’t look safe to drive so I didn’t use it thereafter. They later told me after a diagnostic evaluation that the engine needed to be replaced as the slapping piston rings had scraped the cylinder walls.

I am reporting a progressive oil consumption defect that led to a catastrophic engine failure in my 2018 Audi Q7. The vehicle was purchased Certified Pre-Owned (CPO). I reported the excessive oil use to an Audi dealer. The dealer attempted to address the issue by performing an engine cleaning/flush, but the engine failed shortly afterwards. Over time, the vehicle required frequent top-offs between service intervals. Eventually, the engine suffered a mechanical failure, resulting in a broken exhaust valve and internal engine damage while driving on the highway. The Audi dealer provided a repair estimate of approximately $12,000. Audi of America offered 40% assistance to make the repair, but does not recognize the underlying excessive oil consumption issue. Furthermore, the proposed repair only replaces the damaged valve and related components, but does not address the underlying excessive oil consumption that caused the failure. This means the vehicle may still: •unexpectedly run low on oil, •lose power while driving, •suffer additional internal damage, or •again experience sudden engine failure while driving. These conditions can cause dangerous drivability issues, including loss of acceleration and potential stalling at highway speeds. This appears to be a serious safety-related defect involving lubrication failure, component breakage, and potential loss of power. I am requesting that NHTSA review this issue to determine whether similar failures are occurring in other Audi Q7 vehicles with the 3.0T engine.

Passenger side rear coil spring broken, shocks leaking. Confirmed by dealer. No warning lamps, messages. Potential safety risks include: Suspension compromise with the balance and alignment of the vehicle. There is a risk of loss of control especially with emergency maneuvers or sharp turns. This leads to poor vehicle control, increase risk of roll of vehicle and braking control. Can cause uneven wear on tires which can cause a blow out or loss of grip on roads. The leaking shocks puts stress on other parts of the vehicle. Suspension may not respond correctly if the vehicle were to hit a pothole or make a sudden turn. The broken coil can puncture a tire, causing loss of control which can result in an accident. The vehicle is garaged year round, maintained very well, with no excessive wear and tear.

Electrical SystemMay 2025 · ODI 11661032Details +

The Audi MMI system, which controls almost everything (radio, navigation, vehicle settings etc) shuts down and restarts every few minutes all by itself. The MMI system restarts completely randomly. It started out of nowhere a few months ago and happens whether driving or parked. Since then it is happening more and more frequently, making the system unusable at times (meaning navigation, radio, etc do not work). I'm afraid this issue is in the vehicle's computer and other components of hte car could be faulty, putting myself and other drivers with Audi cars at risk of injury or death if something with the computer fails. I have researched this issue extensively online and this seems to have appeared in numerous different Audi models and years. This also seems to have started happening fairly recently in most cases. I have not and will not take my vehicle to the dealership for diagnosis because I know they will charge a few hundred dollars just to tell me they cannot find anything (this is what many people have already posted online). There is an OBVIOUS computer system issue with Audi vehicles affecting their MMI system and some sort of fix is needed, for the safety of all vehicle owners.

To Whom It May Concern, I am writing to formally report a serious and recurring safety issue involving my 2018 Audi Q7. The vehicle has experienced repeated drive system malfunctions that result in sudden loss of power, reduced acceleration, and warning messages on the dashboard such as “Drive System: Malfunction” and “Electrical System Failure.” These incidents have occurred while the vehicle was in motion, creating a hazardous situation for both the occupants and surrounding drivers. In my case, the vehicle unexpectedly lost power while driving at highway speeds, forcing me to maneuver to the shoulder with diminished control. This sudden malfunction is unpredictable and could easily result in a collision or serious injury, especially in high-speed or high-traffic conditions. Upon researching this issue, I found that numerous other 2018 Audi Q7 owners have reported similar problems. These complaints consistently cite the same symptoms, including sudden deceleration, electrical system errors, and power steering failure. It appears to be a widespread defect that may warrant a recall or further investigation by the NHTSA. I urge your office to investigate this matter promptly to prevent potential injuries or fatalities. I am willing to provide service records, diagnostic codes, photos, or any other documentation that may support this complaint. Thank you for your attention to this serious safety concern. I hope the NHTSA will take appropriate action to ensure the safety of all drivers affected by this defect.

The engine burns oil. At about 60k miles started to burn about a liter every 10k miles. Once the engine got to about 80K engines it started burning a leter about every 1K miles. The high amount of oil consumption fouled the spark plugs, coils, injectors and sensors. This resulted in a drive system malfunction, caused loss of power in the engine that ultimately ruined the engine with less than 100K miles.

Twice, without logically-relevant symptom or warning, when the vehicle attempted to accelerate from a low speed in the middle of a busy intersection, the AEB incorrectly activated, suddenly stopped the vehicle, startled the drivers, and nearly caused accidents. Turned out, this was known behavior caused by a design defect software bug in the "door control modules" for which a software update had been released but never publicly announced. Audi charged us $315 for the software update, but since it is a manufacturing defect causing a critical safety issue, it should be covered by a safety recall, all owners of Audi vehicles with the affected "door control modules" should be proactively notified of the software update and should receive it without cost.

For over 24+ months now, the engine has been showing signs of excessive oil consumption. I've had the engine light come on requesting for me to add a quart of oil...on average, every 2,000 miles. I'm concerned with this excessive oil consumption as it is a major safety issue, as the piston rings may fail due to a possible faulty engine design (most likely since this excessive oil consumption is a frequent occurrence with other drivers of this vehicle). When discussed with the dealership, they are aware of the situation (2017-2019 Audi Q7 excessive oil consumption) and they request that I pay for an engine compression test. This amount of oil consumption shouldn't happen.

A very distracting warning about an issue with a front left side marker keeps popping up - on some rides multiple times in a minute! - and the only way to address it is, according to the dealership, to pay almost $7,000 to replace the entire headlamp assembly. It’s so distracting I do not permit the new teenage driver in our family to drive the car because I do not think it is safe. The visual is alarming and appears in the display immediately behind the steering wheel, so it is distracting. I think it makes a Ping! noise too, each time it appears. The car passed inspection because the light still works, there seems to be some other problem deep in the assembly that is causing the distracting warning. Given the cost and the safety issue from the distraction, I was surprised there is not a recall on this. So, I am reporting it now. Here is the information the dealership provided with the estimate: IMMEDIATE ATTENTION UPON INSPECTION AND DIAGNOSING FOUND LEFT HEADLAMP ASSEMBLY IS DEFECTIVE 450TU FOR HEADLAMP REPLACEMENT 350 TU FOR FRONT CAMERA CALIBRATION REPLACE HEADLAMP ASSEMBLY IS 6,973.89

Error code for right front side marker light faulty. Light seems to be working. I've had two mechanics look at the car. They can't figure out what's wrong. Error message appears randomly. Brakes are very squeaky. I took the car to Audi and they said it was normal and I should brake more aggressively.
